1. Jump between old and new domain names

Scenario: Jump based on domain name, now the old domain name of the company: www. peihua. com

There are business requirements to change, and the new domain name www. zhenguo. com needs to be used instead, but the old domain name cannot be abolished. You need to jump to the new domain name, and the following parameters remain unchanged

Configure dns, configure www. peihua. com (old) and www. zhenguo. com (new) parsing, respectively 


rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

(You must have an official source for yum to install nginx) 


yum install nginx -y
rpm -qc nginx    // Find configuration files

Modify the configuration file of nginx 


[root@localhost ~]# vim /etc/nginx/conf.d/default.conf 

server {
  listen    80;
  server_name www.peihua.com;                            # Domain name modification 

#charset koi8-r;
  access_log /var/log/nginx/peihua.com-access.log main;        # Log modification 

location / {
    # Domain name redirection 
    if ($host = 'www.peihua.com') {
 rewrite ^/(.*)$ http://www.zhenguo.com/$1 permanent;
    }
    root  /usr/share/nginx/html;
    index index.html index.htm;
  }

[root@localhost named]# systemctl restart nginx

Configure domain name resolution 


yum -y install bind

# Modify the master configuration file 
[root@localhost conf.d]# vim /etc/named.conf
options {
    listen-on port 53 { any; };      // Modify to any
    listen-on-v6 port 53 { ::1; };
    directory    "/var/named";
    dump-file    "/var/named/data/cache_dump.db";
    statistics-file "/var/named/data/named_stats.txt";
    memstatistics-file "/var/named/data/named_mem_stats.txt";
    recursing-file "/var/named/data/named.recursing";
    secroots-file  "/var/named/data/named.secroots";
    allow-query   { any; };       // Modify to any

# Modify the zone profile 
[root@localhost conf.d]# vim /etc/named.rfc1912.zones 
zone "peihua.com" IN {
    type master;
    file "peihua.com.zone";
    allow-update { none; };
};

zone "zhenguo.com" IN {
    type master;
    file "zhenguo.com.zone";
    allow-update { none; };
};

# Modify the area data file 
[root@localhost conf.d]# cd /var/named/
[root@localhost named]# cp -p named.localhost peihua.com.zone
[root@localhost named]# cp -p peihua.com.zone zhenguo.com.zone

[root@localhost named]# systemctl start named

Browser testing

Browser input simulates access to http://www. peihua. com/test/1/index. php (although this request content does not exist) jumps to
http://www.zhneguo.com/test/1/index.php, 301 can be seen from headers, which realizes permanent jump, and the parameters after the domain name also jump normally.

2. IP-based access jump

Action Scenario: Based on the client IP access jump, for example, the company business version is launched today, all IP access content will display a fixed maintenance page, only the company IP: 12.0. 0.100 access is normal

Modify the nginx configuration file 


[root@localhost html]# vim /etc/nginx/conf.d/default.conf 

server {
  listen    80;
  server_name www.peihua.com;

 #charset koi8-r;
  charset 'utf-8';                                      // Recognize Chinese characters 
  access_log /var/log/nginx/peihua.com-access.log main;
  # Is the setting legal IP Sign 
  set $rewrite ture;
  # Judge whether it is legal or not IP
  if ($remote_addr = "12.0.0.100") {
 set $rewrite false;
 }
 # Illegal IP Make a judgment and mark it 
 if ($rewrite = ture) {
 rewrite (.+) /maintenance.html;
 }
 # Match the tag to jump to the site 
 location = /maintenance.html {
 root /usr/share/nginx/html;
 }

Add custom page content to maintenance. html 


[root@localhost html]# cat /usr/share/nginx/html/maintenance.html 
<h1> Website under maintenance </h1>

Browser testing

Use ip address 12.0. 0.100 to access http://www.peihua.com, which can be accessed normally
Use IP address 12.0. 0.99 to access http://www.peihua.com to display the maintenance page

3. Jump to the new domain name based on the old domain name and add a directory

Scenario: Based on the old domain name, jump to the new domain name and add a directory. For example, you are now accessing http://bbs.peihua.com.
Now you need to jump all the posts under this domain name to http://www.peihua.com/bbs, and pay attention to keeping the parameters unchanged after the domain name jump

Modify the nginx configuration file 


[root@localhost named]# vim /etc/nginx/conf.d/default.conf 

  listen    80;
  server_name bbs.peihua.com;
  #charset koi8-r;
  charset 'utf-8';
  access_log /var/log/nginx/peihua.com-access.log main;
  location /post {
       rewrite (.+) http://www.peihua.com/bbs$1 permanent;
  }

Note: accp. com. zone needs to change the host domain name resolution from www to bbs 


[root@localhost named]# cd /var/named
[root@localhost named]# vim peihua.com.zone 
$TTL 1D
@    IN SOA @ rname.invalid. (
                    0    ; serial
                    1D   ; refresh
                    1H   ; retry
                    1W   ; expire
                    3H )  ; minimum
    NS   @
    A    127.0.0.1
bbs IN A    12.0.0.25

[root@localhost named]# systemctl restart named
[root@localhost named]# systemctl restart nginx

Browser access

The browser accesses http://bbs.peihua.com/post/a.html, which is called www.peihua.com/bbs/post/a.txt

4. Jump based on parameter matching

Action scenario: Jump based on parameter matching, for example, now visit http://www. peihua. com/100-(100 200)-100. html
Jump to the http://www.peihua.com page

Modify the nginx configuration file 


[root@localhost named]# vim /etc/nginx/conf.d/default.conf 

server {
  listen    80;
  server_name www.peihua.com;
  
  #charset koi8-r;
  charset 'utf-8';
  access_log /var/log/nginx/peihua.com-access.log main;
  
  if ($request_uri ~ ^/100-(100|200)-(\d+).html$) {
     rewrite (.*) http://www.peihua.com permanent;
  }

Note:\ d matches 1 number, between 0 and 9

Modify dns and change bbs to www 


[root@localhost named]# vim peihua.com.zone 
$TTL 1D
@    IN SOA @ rname.invalid. (
                    0    ; serial
                    1D   ; refresh
                    1H   ; retry
                    1W   ; expire
                    3H )  ; minimum
    NS   @
    A    127.0.0.1
www IN A    12.0.0.25

[root@localhost named]# systemctl restart named
[root@localhost named]# systemctl restart nginx

Browser testing

The browser accesses http://www.peihua.com/100-200-26. html, which is called the homepage of www.peihua.com

5. Based on all jumps ending in php and based on a certain 1 page

Modify the nginx configuration file 


yum install nginx -y
rpm -qc nginx    // Find configuration files
0

Browser access

The browser accesses http://www.peihua.com/upload/a.php, which is called www.peihua.com by jump

6. Jump based on a specific 1 page/abc/123. html

Modify the nginx configuration file 


yum install nginx -y
rpm -qc nginx    // Find configuration files
1

Browser access

The browser accesses http://www.peihua.com/abc/123. html, which is called www.peihua.com
